What Omeprazole Sandoz IV is used for

This medicine is used to treat and help heal peptic ulcers.

Depending on the position of the ulcer it is called a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum which is the tube leading out of the stomach.

Ulcers can be caused in part by too much acid being made in the stomach.

This medicine is also used to help prevent gastric or duodenal ulcers from coming back.

Reflux oesophagitis

This medicine is used to treat and prevent reflux oesophagitis. This can be caused by "washing back" (reflux) of food and acid from the stomach into the oesophagus (food pipe).

Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Zollinger-Ellison syndrome

This medicine is also used to treat a rare condition called Zollinger-Ellison syndrome, where the stomach produces very large amounts of acid, much more than in ulcers or reflux disease.

How Omeprazole Sandoz IV works

Omeprazole Sandoz IV belongs to a group of medicines called proton pump inhibitors. It works by decreasing the amount of acid made by the stomach. This does not stop food being digested in the normal way. It helps reduce the pain and also allows the ulcer to heal.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

There is no evidence that this medicine is addictive.

This medicine is available only with a doctor's prescription.
